\ PATTERN MECHANISM FOR LOOMS.

Application filed August 28, 1923. Serial No. 659,760.

To aZZ whom it may concern:

Be it known that 1, WILLIAM J. LUTTON,

a citizen of the United States, and resident of Paterson, in the countyof Passaic and State of New Jersey, have invented a new and usefulImprovement in Pattern Mechanism for Looms, of which the following is aspecification.

This invention relates to a pattern mechanism for looms and moreparticularly to a supplemental mechanism adapted to be combined with ashuttle box pattern chain mechanism and a multiplier pattern chainmechanism of well known construction and operation, by means of whichsupplemental mechanism a different number of picks of filling may beinserted without interfering with the use of the ordinary'box patternchain and multiplier chain mechanisms in 20 the usual way.

This invention consists in certain novel features of construction andarrangement, whereby a pick and pick motion may be produced on a twoweave pattern chain of very few bars and thus materially reducing thecost of the pattern chain also the weight thereof.

A. practical embodiment of my invention is represented in theaccompanying drawings, in which Fig. 1 represents a side elevation of aportion of a loom having my invention applied thereto.

Fig. 2 represents a detailed rear elevation, on an enlarged scale, of myinvention and the parts adjacent thereto.

Fig. 3 represents a vertical section taken inside the frame of the partsshown in Fig. 2, certain portions being broken away to show other partsmore clearly.

Fig. 4 represents a similar view of the parts in another position.

Fig. 5 represents a vertical section taken in the plane of the line V--Vof Fig. 2, looking in the direction of the arrows, and

Fig. 6 represents a vertical section taken in the plane of the lineVI-VI of Fig. 2, looking in the direction of the arrows.

The frame of the loom is denoted by 1, the reciprocating support for thedrop boxes by 2, the lay by 3, the flexible connections by i, whichconnections are arranged to connect the drop boxes and the connectinglevers 5. The vibrator levers 6 are each provided with a mutilated gear7 loosely mounted thereon, and an arm 8, which connects the gear withits connecting lever 55. he heddle operating pattern chain sup portingwheels 9 are secured to rotate with a shaft 10, which is provided with aspur gear. 11 in mesh with a pinion 12 carried by a shaft 13.

A mutilated cylinder gear 14.- fast on the shaft 13 is arranged to coactwith the muti-- lated gears 7. A similar mutilated cylinder gear 15fixed on a shaft 16 also coacts with the gears 7. The mutilated cylindergear 14 is driven from a vertical shaft v17 through mitre gears 18, 19,while the mutilated cylinder gear 15 receives its motion from thevertical shaft 17 by means of mitre gears 20. 21.

The parts to which I have thus briefly alluded are well known in theart, combined and arranged substantially as shown, and it is not thoughtnecessary to give a detail statement of their operation, since the sameiswcll known to those skilled in the art, my present inventionpertaining to certain, means for controlling the operation of the abovenamed parts in order to multiply the effect of a supplemental shuttlebox pattern chain on the pattern chain, thereby saving length of chain.

The shuttle box pattern chain mechanism comprises a cylinder 22 fast ona sleeve 28 mounted on the shaft 10. The cylinder 22 has mounted thereona box pattern chain 24: made up of links and bars carrying mutilatedrolls and tubes for the shuttle box indicator levers in the usualmanner.

Connected with the sleeve 23 is a starwheel 25 which is operated by apinwheel 26 splined on a shaft 27 driven from the shaft 13 by means ofgears 28, 29. The sleeve 30 having the multiplier pattern chain cylinderis mounted on the shaft 10 and carries a multiplier chain 31 which iscomposed of links and bars carrying rolls and tubes in the usual manner.The sleeve 30 also has a star-wheel 32 which is operated by a pinwheel33 splined on the shaft 27 A longitudinally movable rod 34 is mounted insuitable bearings and carries a forked arm 35, which engages an annularrecess in the hub of the pinwheel 26, to move the pinwheel. into and outof engagement with the .starwheel 25. A collar 36 is fixed on thelongitudinally movable rod 84, which collar has 1 a notch 37 arranged toreceive theupper end of a lever 38 pivoted at 39 on a stationary rod 40,which is supported in a lug 4:1 on the frame 1. The lever 38 is providedwith an-arn'i 42ywhich depends below the pivot 39 n1 position to receiveone end of a helically coiled retraction spring 43. A second arm 44projects from the lever 38 and is connected through a connector 15 withan indicator lever 16, pivotally supported at at? andarranged to extendover the multiplier pattern chain 31. By reason of the rotary motionofthe n' nltiplier pattern chain a roller 4:8'or a tube 49 will passunder the indicator lever 16 and through the connector 15, moveithelever 38 and with it the longi tudinal moving rod 3t,to carry thepinwheel 26iinto andout of engagement with the starwheel 253therebycausing the rotation of the box pattern chain cylinder 22 and the boxpattern chain 2 1 in the usual manner.

A second longitudinally movable rod 50, mounted in suitable bearings,has attached thereto a forked lever 51, which engages an annular recessin the hub of the pinwheel A collar 52 is fixed on the longitudinallymovable rod and has a notch 53 arranged to receive the upper end ofv alever 54: pivoted at 55, on the stationary rod 10. A downwardlyextending arm 56 of the lever 54 has attached thereto one end of ahelically coiled retraction spring 57, while the other end engages a lug58 depending from a collar 59 fast on the rod 40. An arm 60 extendsontwardly from the lever 5 1 in position to receive the lower end of aconnector 61; the upper end of the connector 61 is bent to form anindicator lever 62, which extends over the box pattern chain 2% and isadapted to be engagedby a mutilated roll (it. The rotary movement of thebox pattern chain 24;,will through the engagement of the mutilated 'roll64 with the lever 62, raise the lever and by reason of the movement ofthe connector 61 move the rod 50 to carry the pinwheel 33 into and outof engagement with the star-wheel 32, thereby causing the star-wheel torotate and actuate the multiplier chain 31. The lowering of the illdl"cator lever 62 will, through the connections of the pinwheel 83 move thepinwheel to disengage it"from the star-wheel 32, and leave thestar-wheel and the multiplier pattern chain 31 at rest.

Extending over the box pattern chain 2% is an indicator lever 65, oneend of which is pivoted on a rod 66, whichis also the fulcrum of thevibrating levers 6, and the other end turned downwardly in position toengage bars 67 of the box pattern chain 24, which project into the pathof the indicator lever. This lever is normally held at the limit of itsdownward movement by a link 68' which connects the lever with a bellcrank to-receiv'e' -the other end of the spring 43'.

A. supplemental shuttle ,box pattern chain 71, made up of links and barscarrying roller, is mounted on a cylinder 72 fast on a shaft 7 3, whichis journalled in the frame 1. One end of the shaft 73 has a gear 74keyed thereon and arranged to mesh with the gear 11 fast on the'shaft10. A series of rocking levers 75 are arranged to extend over and beengaged by the rollers or bars of tie supplemental box pattern chain 71.Each of the rocking levers 75 is'provided at one end with an invertedU-shaped slot 76 which normally rests upon a rod77 carried by theframe 1. This rod serves as the fulcrum upon which the rocking leversmay oscillate. The rocking levers are held in position on the rod 77 bymeans of an oscillating arm 78 which is loosely mounted on a shaft 7 9journalled in a bracket 80 carried by the frame 1. The other end of eachof the rocking levers is connected to the vibrator levers 6 by a link81, so that as the rocking levers are acted upon by the rolls or bars ofthe supplemental box pattern chain 71, the vibrating lever 6 will bemoved accordingly, and the mutilated gears 7 brought into position tomesh with either of the mutilated cylinders gears 14, 15 and actuate theconnecting levers 5 and hence, the drop box support for the shuttles(not shown).

The rocking levers 75 are intermittently rendered inoperative by meansof the extended bars 67 of the box pattern chain 24, which bars engageand lift the lever 65 which in turn is connected to the oscillating arm78 by a strap 82. hen the oscillating arm '78 is raised, the rockinglevers 75 will be free to move away from the rod 77 so that when therolls on the supplemental chain act upon the rocking levers they will.be lifted from their fulcrum on the rod 77, as clearly shown in Fig. 4.After the extended bar 67 has passed from beneath the lever 65 thespring 43 actuates the bell crank'lever 69, link 68, strap 82 and exertsa pressure on the oscillating arm 7 8 which returns the U-shaped' endsof the rocking levers 75 to the rod 77.

In operation:

Assuming the parts to be in the position shown in Figs. 1, 2, 3, 5 and6, the supplemental pattern chain 71 is driven from the pinion 12through the spur gear '11 on the shaft 10 and the gear 74 fast on theshaft 73. As the rolls on the supplemental chain are brought intoposition to act upon the rocking levers 75, the vibrators 6 through thelinks 81, which connect the levers 75 and vibrators 6, will actuate therespective shuttle box mechanism. In the revolution of the shuttle boxpattern chain 2 1, the extended bars 67 will be moved intoposition toengage and lift the lever 65 which in turn will rock the oscillating arm78 through the strap 82. which connects the lever 65 and oscillating arm78. When the oscillating arm 78 is raised, the rocking levers '75 arefree to be lifted from the rod 77, to the position shown in Fig. 4, sothat as the rolls on the supplemental chain come into contact with therocking levers 75, the slotted end of the levers 7 5, which waspreviously the fulcrum, will be raised and the upper end of the links81, which are connected to the levers and vibrators, will form thepivots on which the rocking levers 75 swing.

In the passing of the extended bar 67 from the lever 65, the springactuated bell crank lever 69, with its link 68, will cause the lever 65,strap 82 and oscillating arm 7 8 to move downwardly to their normalpositions.

The downward movement of the oscillating arm 78 will press upon therocking levers 7 5 until the slots 76 in the end of the levers 75 areagain seated on the rod 77, whereupon the rolls on the supplementalchain '71 will rock the levers 75 on the rod 77 which in turn actuat-esthe links 81, the vibrators 6 and their adjacent mechanisms.

From the foregoing it will be understood that, when the pinwheel 26 isin engagement with the star-wheel 25, as shown in Figs. 1, 2, 3, 5 and6, the box pattern chain 24 will be rotated until the mutilated roll64-, carried by the box pattern chain 24 comes under the lever 62. Thisroll 64 raises the lever 62, actuates the connector 61, which in turnmoves the rod 50 and pinwheel 33 into engagement with the star-wheel 32which rotates the multiplier pattern chain 31. During the revolution ofthe multiplier pattern chain 31, the box pattern chain will remainstationary until the multiplier pattern chain 31 causes the next roll 48to come under and actuate the indicator lever 46. The movement of thisindicator lever 46 will raise the connector 45, rock the lever 38 withits longitudinal rod 34 and pinwheel 26, which pinwheel 26 will moveinto engage l'nent with the star-wheel 25, which again actuates thecylinder 22 and box pattern chain 24-. Thus it will be seen that whilethe box pattern chain 24 is at rest, the multiplier pattern chain 31will continue in motion, and when the box pattern chain 24 is broughtinto action the multiplier pattern chain 31 will remain idle.

The mechanism for controlling the opera tion of the supplemental boxpattern chain may be actuated in conjunction with the mu- I tilated roll64, by placing the extended bars 67 on the box pattern chain incooperative relation with the mutilated roll 64, or in other words, thebars carrying the mutilated roll 64 may be lengthened to form theextended portions 67; Thus it will be seen that the box pattern chainwill bring the extended bars 67 into contact with the lever 65, whichwill be lifted, and by reason of the strap 82, raise the oscillating arm78 to the position shown in Fig. 4. When this oscillating arm '78 israised, the rocking levers75. which are connected to the vibrator 6,will be free to mov away from the rod 7 7, so that the rolls on thesupplemental box pattern chain 71 will lift the rocking levers 75 attheir fulcrums and thereby render the vibrators 6 and their respectiveshuttles inoperative. At this time, the shuttle box called in by the boxpattern chain 24 will remain stationary in line with the raceway and theshuttle of that box operated until themultiplier pattern chain 31 againbrings in a roll 48 to actuate the lever 46, which in turn through itsadjacent mechanism will move the pinwheel 26 into engagement with thestar-wheel 25 thereupon setting the box pattern chain 24 in motion andallowing the mechanism to rock the fulcrum of the levers 75 on the rod77, and the supplemental box pattern chain-71 tooperate the shuttles asdesired. 1

My invention shown and described sets forth a loom having a pick andpick motion on a two weave pattern chain and'by reason of theconstruction and arrangement of the supplemental shuttle box patternchain with the adjacent mechanism, the chain may be automatically throwninto and out of operation, thereby controlling the pick and pick partof: the pattern. When thrown out of operation the work of filling thepattern is placed upon the shuttle box pattern chain,

allowing a run ofone or more shuttles in connection with the multiplierpattern chain mechanism, as desired.

The advantages of my improvements will be readily perceived by thoseskilled in the art, and may be easily applied to box pattern chain andmultiplier chain mechanisms of ordinary and well known construction.

I desire it to be understood that various changes may be resorted to inthe form, construction and arrangement of the several parts withoutdeparting from the spirit and scope of my invention; hence, I do notin.- tend to be limited to the details herein shown and described exceptas they may be included in the claims.
